The Expansion of the Panama Canal

The Expansion of the Panama Canal (Third Set of Locks Project)  is a project that will double the capacity of the Panama Canal by 2014 by allowing more and larger ships to transit. Then-Panamanian President Martín Torrijos presented the plan on April 24, 2006 and Panamanian citizens approved it in a national referendum by 76.8% of the vote on October 22, 2006.

The project creates a new lane of traffic along the Canal by constructing a new set of locks. Details of the project include the following integrated components:
  • Construction of two lock complexes—one on the Atlantic side and another on the Pacific side—each with three chambers, which include three water-saving basins;
  • Excavation of new access channels to the new locks and the widening of existing navigational channels; and,
  • Deepening of the navigation channels and the elevation of Gatun Lake's maximum operating level.
On September 3, 2007, after approval by the Cabinet, National Assembly and referendum, the Panama Canal expansion project officially started. Panama's then-president Martín Torrijos stated that the Canal will generate enough wealth to transform Panama into a First World country. The project is also expected to reduce poverty by about 30%, resulting in an 8% poverty rate in Panama afterwards.

The capacity of the Panama Canal is determined by a number of factors, of which the most important is the size of the locks that raise and lower ships as they pass through the canal. The smallest dimensions of the locks are 110 ft (33.53 m) wide, 1,050 ft (320.04 m) long, and 85 ft (25.91 m) deep. Because of clearance issues, the usable sizes are somewhat smaller (for example, the maximum usable length of each lock chamber is about 1,000 ft (304.8 m). The maximum size of the ships that can transit the canal is known as the Panamax.

Since the 1930s, all of the Canal widening studies have determined that the most effective and efficient alternative to enhance Canal capacity is the construction of a third set of locks, with bigger dimensions than those of the locks built in 1914. In 1939, the United States initiated the construction of locks designed to allow the transit of commercial and war ships, whose dimensions exceeded the size of the existing locks. In 1942, after advancing the excavations significantly, the Americans suspended the third set of locks project because of the outbreak of World War II. In the 1980s, the tripartite commission formed by Panama, Japan, and the United States took up the issue again, and like the Americans in 1939, determined that a third set of locks with larger lock chambers was the most appropriate alternative for increasing Canal capacity. Today, the studies developed by the Panama Canal Authority (ACP) as part of its Master Plan, with a horizon to the year 2025, confirm that a third set of locks, larger than those existing now, is the most suitable, profitable and environmentally responsible way to increase Canal capacity and allow the Panamanian maritime route to continue to grow.

Throughout its history, the Canal has continually transformed its structure and adjusted to trade requirements and international maritime transport technologies. In this manner, the Canal has managed to increase its competitiveness in a sustainable manner.

Then-President Torrijos in his speech on April 24, 2006, announcing the project, said that "…to say it in a graphic manner, [the Canal] is like our 'petroleum'. Just like the petroleum that hasn't been extracted is worthless, and that in order to extract it you have to invest in infrastructure; the Canal requires to expand its capacity to absorb the growing demand of cargo, and generate more wealth for Panamanians".

Cargo volume

On the basis of ACP's projections, during the next 20 years, cargo volume transiting the Canal will grow at an average of three percent per year, doubling 2005's tonnage by the year 2025. As such, providing the Canal with the capacity to transit larger vessels will make it more efficient by allowing the transit of higher cargo volumes with relatively fewer transits and less water use.

Historically, the dry and liquid bulk segments have generated most of the Canal's revenues. Bulk cargo includes dry goods, such as grains (corn, soy and wheat, among others), minerals, fertilizers, coal, and liquid goods, such as chemical products, propane gas, crude oil and oil derivatives. Recently, the containerized cargo segment has replaced the dry bulk segment as the Canal's main income generator, moving it to second place. On the other hand, the vehicle carriers segment has become the third income generator, replacing the liquid bulk segment. Shipping industry analysis conducted by the ACP and top industry experts indicate that it would be beneficial to both the Canal and its users to expand the Canal because of the demand that will be served by allowing the transit of more tonnage.

The question is, however, whether the trend upon which the Panama Canal Authority makes those projections can continue for a generation.

The growth in Panama Canal usage over the past few years has been almost entirely driven by increased U.S. imports from China passing through the canal en route to ports on the U.S. East and Gulf Coasts. But it is increasingly recognized in both the United States and China that this imbalance in trade is unsustainable and will be reduced in some sort of adjustment in the coming years, though it is important to note that any such imbalance need not be made up by physically shipped goods, but could be made by other trade such as intellectual property as China upgrades its intellectual property protection laws. The ACP, however, presumes that it will not only not be adjusted, but will continue to grow for a generation as it has for the past several years. One of the central points of the canal expansion proposal's critics, most prominently made by former canal administrator Fernando Manfredo, is that it's unrealistic to attempt to predict canal usage trends over a generation, most improbable to expect that U.S. imports from China will continue to grow as they have the past few years over a generation, and irresponsible to bet Panama's financial future on such a projection.


The most direct competition to the Canal is from alternative routes which present options for the transport of cargo between the same geographical points of origin and destination.

The opening of the Northwest Passage to commercial traffic could pose an alternative to the Canal in the long term. It is thought that global warming is likely to open the passage for increasing periods of time, making it attractive as a major shipping route. However the passage through the Arctic Ocean would require significant investment in escort vessels and staging ports. Therefore the Canadian commercial marine transport industry does not anticipate that this route will be a viable alternative to the Panama Canal within the next 10 to 20 years.

The two main current competitors of the Panama Canal are the U.S. intermodal system and the Suez Canal. The main ports and merchandise distribution centers in these routes are investing in capacity, location, and maritime and land infrastructure to serve Post-Panamax container ships and handle their cargo volumes. According to the ACP, the growing trend to use such ships in transcontinental routes competing with the canal is irreversible. If so, by the year 2011, approximately 37% of the capacity of the world's container ship fleet will consist of vessels that do not fit through the current canal, and a great part of this fleet could be placed in routes that compete with Panama.

The proposal states that strengthening its competitive position will allow the canal to accommodate demand and serve its customers. If the canal were to have the capacity to serve the growing demand, Panama could be transformed into the most important connectivity hub in the continent by joining together at the isthmus the north–south continental routes with the east-west transcontinental routes. Accordingly, the canal will continue to be viable and competitive in all of its routes and segments, and contribute significantly to Panama's development and growth while maintaining its position as one of the main world trade routes.


According to the ACP, the canal will reach its maximum sustainable capacity between the years 2009 and 2012. When it reaches this capacity it will not be able to continue to handle demand growth, resulting in a reduction in the competitiveness of the Panama maritime route

As approved by the Panamanian people, construction for the expansion project is slated to conclude by 2014. All creative means will be employed by the ACP to stretch capacity until the construction is done.
The proposed expansion of the canal by the construction of a third set of locks will allow it to capture the entire demand projected through 2025 and beyond. Together, the existing and new locks will approximately double the capacity of the present Canal.

Critics such as former legislator Dr. Keith Holder, co-author of the legislation that created the ACP, point out that canal usage is seasonal and that even during the few months when it is most crowded the bottleneck that slows traffic is not the locks but the narrow Culebra Cut, in which there is a limited capacity for large ships to pass one another.

Although the Canal is reaching its maximum capacity, the ACP clarifies that this does not mean that ships will be unable to transit the Canal. However, it does mean that the Canal's growth capacity will stagnate and that it will not capture additional cargo volumes.

The former head of the Panama Canal's Dredging Division, Thomas Drohan, who is a critic of the expansion plan, discounts allegations that this is a problem in the short term—he argues that if the supply of any good or service becomes short, any business can raise its price for it and this would apply to Panama Canal tolls as much as it does to petroleum.

The project


The Canal today has two lanes each with its own set of locks. The proposal consists of adding a third lane through the construction of lock complexes at each end of the Canal. One lock complex will be located on the Pacific side to the southwest of the existing Miraflores Locks. The other complex will be located to the east of the existing Gatun Locks. Each of these new lock complexes will have three consecutive chambers designed to move vessels from sea level to the level of Gatun Lake and back down again. Each chamber will have three lateral water-saving basins, for a total of nine basins per lock and 18 basins total. Just like the existing locks, the new locks and their basins will be filled and emptied by gravity, without the use of pumps. The location of the new locks uses a significant portion of the area excavated by the United States in 1939 and suspended in 1942 because of the start of World War II. The new locks will be connected to the existing channel system through new navigational channels.
The new lock chambers will be 1,400 ft (426.72 m) long, by 180 ft (54.86 m) wide, and 60 ft (18.29 m) deep. They will use rolling gates instead of miter gates, which are used by the existing locks. Rolling gates are used in almost all existing locks with dimensions similar to those being proposed, and are a well-proven technology. The new locks will use tugboats to position the vessels instead of locomotives. As in the case of the rolling gates, tugs are successfully and widely utilized for these purposes in locks of similar dimensions.

Navigational channels

According to the plan, a 3.2 km (2.0 mi)-long access channel will be excavated to connect the new Atlantic locks with the existing sea entrance of the Canal. To connect the new Pacific-side locks with the existing channels, two new access channels will be built:
  • The north access channel, which will connect the new Pacific-side lock with the Gaillard Cut, circumventing Miraflores Lake, and which will be 6.2 km (3.9 mi) long; and,
  • The south access channel, which will connect the new lock with the existing sea entrance on the Pacific Ocean, and which will be 1.8 km (1.1 mi) long (see figure 5). The new channels will be at least 218 meters (715 ft) wide, both on the Atlantic and Pacific sides, which will permit Post-Panamax vessels to navigate in these channels in a single direction at any time.

Gatun Lake raised 1.5 feet (0.46 m)

All Canal elevations are referred to Precise Level Datum (PLD), which is close to Atlantic and Pacific entrance mean sea level. The maximum operational level of Gatun Lake will be raised by approximately 0.45 meters (1.5 ft) — from the present PLD level of 26.7 meters (87.5 ft) to a PLD level of 27.1 meters (89 ft). Combined with the widening and deepening of the navigational channels, this component will increase Gatun Lake's usable water reserve capacity and will allow the Canal's water system to supply a daily average of 165,000,000 US gal (625,000,000 L; 137,000,000 imp gal) of additional water. This additional water volume is enough to provide an annual average of approximately 1,100 additional lockages without affecting the water supply for human use, which is also provided from Gatun and Alhajuela Lakes.

Construction timeline

The construction of the third set of locks project is slated to take between seven to eight years. The new locks could begin operations between fiscal years 2014 and 2015, roughly one hundred years after the canal first opened.


The main purpose of the Canal expansion program is to increase Panama's ability to benefit from the growing traffic demand. This growing demand is manifested both in increased cargo volume and vessel size that will use the Panama route. In this sense, the Canal, with a third set of locks, will be able to manage the traffic demand forecast beyond 2025, and total revenues for that year, adjusted for inflation, will amount to over USD $6.2 billion.

Estimated cost

The cost to construct the third set of locks is estimated by the ACP at approximately US $15 to 25 billion. This estimate includes design, administrative, construction, testing, environmental mitigation, and commissioning costs. Additionally, this cost includes contingencies to cover risks and unforeseen events, such as those that might be caused by accidents, design changes, price increases, and possible delays, among others. The most relevant program cost is that of constructing the two new lock complexes – one on the Atlantic side and the other on the Pacific side – with estimated costs of approximately US $1.110 billion and US $1.03 billion each, plus a US $590 million provision for possible contingencies during their construction.

Opponents contend the project is based on uncertain projections about maritime trade and the world economy. Prof. R.N. Mendez, an economist who works for the University of Panama, alleged that the economic and financial projections are based on manipulated data. Independent engineers, most notably Humberto Reynolds and Tomas Drohan Ruiz, the former head of Engineering and Dredging of the Panama Canal, say that the project will cost much more than currently budgeted and that it is too risky for Panama.
M.A. Bernal, professor at the University of Panama, thinks that confidence in the budget of the Panama Canal Authority is undermined because of engineering and consultancy firm Parsons Brinckerhoff's involvement. Parsons Brinckerhoff is best known for the Big Dig in Boston, which ended up costing three times the estimated amount with several structural and safety concerns.

Estimated profit

According to the ACP, the third set of locks is financially profitable, producing a 12% internal rate of return. The third set of locks project is self-financed and its financing will be separate from the Government's financing. The state will not guarantee or endorse any loans undertaken by the ACP for the project's execution. With tolls increasing at an annual average rate of 3.5% for 20 years, and according to the most probable traffic demand forecast and construction schedule, the external financing required will be mainly temporary and on the order of USD $2.3 billion to cover peak construction activities between 2009 and 2011. With the cash flows generated by the expanded Canal, investment costs will be recovered in less than 10 years and financing could be repaid in approximately eight years.
What "self-financing" actually means, however, is disputed. At least half of the money needed for the canal expansion project will have to be borrowed, and the ACP does not calculate the interest on that as part of the project's costs.
The ACP's revenue projections are based on suppositions about increase in canal usage and the willingness of shippers to pay higher tolls instead of seeking competing routes, both of which critics question.

Environmental Impact

The ACP claims in the proposal that the third set of locks project is environmentally viable. It has been found that all possible adverse environmental impacts can be mitigated through existing procedures and technology, and no immitigable or permanent adverse impacts on the population or the environment are anticipated. There are no elements within the scope of the project that will compromise its environmental viability, such as communities, primary forests, national parks or forest reserves, relevant patrimonial or archaeological sites, agricultural or industrial production areas, or tourist or port areas. The project will not cause permanent or irreversible impacts on water or air quality. The proposed water supply program fulfills the objectives of maximizing the water capacity of Gatun and Alhajuela Lakes, and applies the most efficient water utilization technology at the locks so no new reservoirs will be required. Consequently, it will not be necessary to relocate communities. The entire area directly affected by the project is located within ACP operational and administrative areas.

Critics to the project contend there are a lot of environmental topics to be considered. For example: link between El Niño (ENSO) and global warming threat to water supplies. The ACP has commissioned a number of studies by a number of consultants about water supply and quality issues, and some like Eric Jackson (editor of the Panama News internet newspaper), Gonzalo Menendez(former head of the National Environmental Authority or ANAM by its Spanish initials), Ariel Rodriguez (University of Panama biologist), former Vice Minister of Public Works Grettel Villalaz de Allen and others are some of the most prominent critics of the canal expansion plan from the point of view of water quality issues. Jackson contends that ACP's public statements often do not match the findings of their studies. He says that the Delft Hydraulics, WPSI Inc, and DHI studies all say that no matter what is done to mitigate the problem, the water saving basins feature of the proposed new locks would increase the intrusion of salt water into Gatun Lake, from which about half of Panama's population takes its drinking water. The chosen method to partially mitigate this problem is to "flush" the new locks with fresh water from Gatun Lake — but that tends to defeat the proposed new locks’ water saving feature and raises questions about the security of the urban water supply.
However, one of the leading environmental organizations in Panama, ANCON (National Association for Nature Conservation) says that the studies and projections of operation of the Third Lock, including the water saving basins, state in a credible manner that there will be very low levels of salinization of waters of Gatun Lake and that these levels would preserve the biologic separation of the oceans with the safekeeping of the biodiversity and water quality for human use.

Employment generation

According to the ACP, the Canal expansion's impact on employment will first be observed in the jobs directly generated by the economic boom experienced during the years of its construction. Approximately 35,000 to 40,000 new jobs will be created during the construction of the third set of locks, including 6,500 to 7,000 additional jobs that will be directly related to the project during the construction's peak years.
However, officials state that the most important impact on employment will be medium and long term and will come from the economic growth brought about by extra income generated by the expanded Canal and the economic activities produced by the increase in Canal cargo and vessel transits – all of these contributing to fully leverage the advantages of Panama's geographic position.
The labor required for construction of the third set of locks will, in its vast majority, be done by Panamanians. To ensure the availability of Panamanian labor necessary for the third set of locks project and its connected activities, the ACP and public and private authorities will work jointly to train the required workforce with sufficient lead time, so that it has the necessary competencies, capabilities and certifications. The amounts necessary to carry out these training programs are included in the cost estimates of the project.

Critics dismiss this as pure demagogy, noting that by the ACP's own studies at the peak of construction there will be fewer than 6,000 jobs created and that some of these will be highly skilled posts filled by foreigners because there are no Panamanians who are qualified to fill them.
Among those who oppose the canal expansion proposal is Panama's construction workers' union, SUNTRACS. The union's secretary general, Genaro Lopez, argues that while some construction jobs would be created by the project, the debt that Panama incurs to build a third set of locks would not be defrayed by increased canal usage and thus an increased part of canal revenues would go toward paying the debt, reducing the waterway's contributions to the national government's general fund and in turn reducing money for road projects, public schools, police protection and all other government services.
Critics also claim the project lacks an accompanying social development plan. Then-President Torrijos has since accepted the request to develop one with the mediation of the United Nations Development Programme.

Voices supporting the project

ANCON (National Association for Nature Conservation) has given its approval of the environmental studies of the proposal and stated some recommendations if the project is approved. The following have also endorsed the proposal:

Voices against the project

Former President Jorge Illueca, former sub-administrator of the Panama Canal Commission, Fernando Manfredo, shipping consultant Julio Manduley and industrial entrepreneur George Richa M. say that the expansion is not necessary; they claim that the construction of a mega-port on the Pacific side would by itself be sufficient to meet probable future demand. The logic behind this is that said port would be the second port (the first being Los Angeles) deep enough in the American Pacific capable of handling post-panamax ships. As Panama is already a natural trading route, it would be able to handle the movement of containers from the Pacific to the Atlantic side via railroad, where containers would be reloaded to other ships for worldwide distribution. In addition, the following organizations and people oppose the project:
  • The Council on Hemispheric Affairs (COHA) stated in a press release that under the Torrijos government, the expanding Panama Canal will not likely serve the needs of the vast majority of Panamanians. Much of the benefits will be tied to the commercial interests of the country's accountants, bankers and lawyers, as well as their U.S. counterparts, and world trade. They also say that the administration's rampant corruption and other flaws raise questions about Panama's capacity to supervise such an enormous project. COHA has received some letters which point out factual errors and plans to modify its statement to reflect this.
  • Former President Guillermo Endara and his Vanguardia Moral de la Patria Party,MOLIRENA, a conservative, business oriented party that normally gets about 10 percent of the vote.
  • Most of the Panamanian left and most of the labor movement, including for example CONUSI(National Independent Syndicate Union) and FRENADESO (National Front for the Defence of Social and Economic Rights).
  • Most members of the nationalistic Panameñista Party (Grettel Villalaz de Allen and Gonzalo Menendez, mentioned above, and former legislator Gloria Young are prominent examples).
  • Some environmentalist leaders and groups: Biodiversidad Panama, whose principal leader is University of Panama biologist Ariel Rodriguez, and former National Environmental Authority director Gonzalo Menendez.
  • Proponents of Liberation Theology, in part because they suspect that poor farmers among whom they have a social base would be adversely affected. The canal expansion issue has aggravated the breach between this mainly Catholic strain and the Catholic hierarchy. This group has chosen the radical Catholic priest Father Conrado Sanjuras as its principal spokesperson for relations with the Electoral Tribunal.

Panama Canal Locks

The Panama Canal Locks, which lift ships up 25.9 m (85 ft) to the main elevation of the Panama Canal, were one of the greatest engineering works ever to be undertaken at the time, eclipsed only by other parts of the canal project. No other concrete construction of comparable size was undertaken until the Hoover Dam in the 1930s. The total length of the lock structures, including the approach walls, is over 3 kilometres (nearly two miles).
The locks, which have a total of six steps, limit the maximum size of ships which can transit the canal, known as Panamax. Each of these steps has two lock chambers, doubling the amount of traffic that can be handled; together they raise ships from sea level to a height of 25.9 m (85 ft).
The locks are to be expanded in the near future to allow more and larger ships to use the canal.

There are three sets of locks in the canal. A two-step flight at Miraflores, and a single flight at Pedro Miguel, lift ships from the Pacific up to Lake Gatun; then a triple flight at Gatun lowers them to the Atlantic side. All three sets of locks are paired; that is, there are two parallel flights of locks at each of the three lock sites. This, in principle, allows ships to pass in opposite directions simultaneously; however, large ships cannot cross safely at speed in the Gaillard Cut, so in practice ships pass in one direction for a time, then in the other, using both "lanes" of the locks in one direction at a time.
The lock chambers are 33.53 meters (110 ft) wide by 320.0 meters (1050 ft) long, with a usable length of 304.8 metres (1000 ft). These dimensions determine the maximum size of ships which can use the canal; this size is known as Panamax. The total lift (the amount by which a ship is raised or lowered) in the three steps of the Gatun locks is 25.9 m (85 ft); the lift of the two-step Miraflores locks is 16.5 m (54 ft). The single-step Pedro Miguel lock has a lift of 9.5 m (31 ft). The lift at Miraflores actually varies due to the extreme tides on the Pacific side, between 13.1 m (43 ft) at extreme high tide and 19.7 m (64.5 ft) at extreme low tide; the tides on the Atlantic side, however, are very small.
The lock chambers are massive concrete structures. The side walls are from 13.7 to 15.2 metres (45 to 55 feet) thick at the bases; towards the top, where less strength is required, they taper down in steps to 2.4 m (8 ft). The centre wall between the chambers is 18.3 m (60 ft) thick, and houses three long galleries which run the full length of the centre wall. The lowest of these is a drainage tunnel; above this is a gallery for electrical cabling; and towards the top is a passageway which allows operators to gain access to the lock machinery.

Filling and draining
Each lock chamber requires 101,000 m3 (26,700,000 US gal; 22,200,000 imp gal) to fill it from the lowered position to raised; the same amount of water must be drained from the chamber to lower it again. Embedded in the side and centre walls are three large water culverts, which are used to carry water from the lake into the chambers to raise them, and from each chamber down to the next, or to the sea, to lower them. These culverts start at a diameter of 22 ft (6.71 m), and reduce 18 ft (5.49 m) in diameter — large enough to accommodate a train. Cross culverts branch off from these main culverts, and run underneath the lock chambers to openings in the floors. There are fourteen cross culverts in each chamber, each with five openings; seven cross culverts from the sidewall main culverts alternate with seven from the centre wall culvert.
The water is moved by gravity, and is controlled by huge valves in the culverts; each cross culvert is independently controlled. A lock chamber can be filled in as little as eight minutes; there is significant turbulence in the lock chamber during this process

The gates
The gates which separate the chambers in each flight of locks must hold back a considerable weight of water, and must be both reliable and strong enough to withstand accidents, as the failure of a gate could unleash a catastrophic flood of water downstream.
These gates are of enormous size, ranging from 47 to 82 ft (14.33 to 24.99 m) high, depending on position, and are 7 ft (2.13 m) thick; the tallest gates are required at Miraflores, due to the large tidal range there. The heaviest leaves weigh 662 t (730 short tons; 652 long tons); the hinges themselves each weigh 16.7 t (36,817 lb). Each gate has two leaves, 65 ft (19.81 m) wide, which close to a V shape with the point upstream; this arrangement has the effect that the force of water from the higher side pushes the ends of the gates together firmly. The gates can only be opened when, in the operating cycle, water level on both sides is equal.
The original gate machinery consisted of a huge drive wheel, powered by an electric motor, to which was attached a connecting rod, which in turn attached to the middle of the gate. These mechanisms were replaced with hydraulic struts beginning in January 1998, after 84 years of service. The gates are hollow and buoyant, much like the hull of a ship, and are so well balanced that two 19 kW (25 hp) motors are enough to move each gate leaf; if one motor fails, the other can still operate the gate at reduced speed.
Each chamber also contains a pair of auxiliary gates which can be used to divide the chamber in two; this is designed to allow for the transit of smaller vessels — such as canal tugs — without using the full quantity of water. They were originally incorporated because the overwhelming majority of all ships of the early 1900s were less than 600 ft (183 m) in length, and would therefore not need the full length of the lock chamber. Nowadays these gates are rarely used; instead, small boats such as tour boats, tugs, and yachts are passed in groups

Safety features
A failure of the lock gates — for example, caused by a runaway ship hitting a gate — could unleash a flood on the lands downstream of the locks, as the lake above the locks (Gatun Lake or Miraflores Lake) drains through the lock system. Extra safety against this is provided by doubling the gates at both ends of the upper chamber in each flight of locks; hence, there are four gates in each flight of locks which would have to fail to allow the higher level of water to pass downstream. The additional gates are 21 m (70 ft) away from the operating gates.
Originally, the locks also featured chain barriers, which were stretched across the lock chambers to prevent a ship from running out of control and ramming a gate, and which were lowered into the lock floor to allow the ship to pass. These fender chains featured elaborate braking mechanisms to allow a ship up to 10,000 tons to be safely stopped; however, given the precise control of ships made possible by the mules, it was very unlikely that these chains would ever be required. With many modern canal users being over 60,000 tons, and given the expense of maintaining them, the fender chains were reduced in number in 1976 and finally removed in 1980.
Beyond this, the original design of the locks had yet another safety feature — emergency dams which could be swung across the locks at the upper end of every flight. These consisted of swinging bridges, from which girders were lowered to the lock floor; steel shutters could then be run down these girders to block the flow of water. Monthly drills were held, by night and day, to make sure that these dams could be deployed in an emergency.
In the late 1930s, the original dams were replaced by new dams, which were raised out of slots in the bottom of the lock chambers, either hydraulically or by compressed air. The new dams were themselves retired in the late 1980s, and today, no emergency dams are in place

Since all the equipment of the locks is operated electrically, the whole process of locking a ship up or down can be controlled from a central control room, which is located on the centre wall of the upper flight of locks. The controls were designed from the outset to minimise the chances of operator error, and include a complete model of the locks, with moving components which mirror the states of the real lock gates and valves. In this way, the operator can see exactly what state the locks and water valves are in.
Mechanical interlocks are built into the controls to make sure that no component can be moved while another is in an incorrect state; for example, opening the drain and fill valves of a lock chamber simultaneously


The project of building the locks began with the first concrete laid at Gatun, on August 24, 1909, by Philadelphia based company Day & Zimmermann (formerly known as Dodge & Day).
The locks at Gatun are built into a cutting made in a hill bordering the lake, which required the excavation of 3,800,000 m³ (5,000,000 cubic yards) of material, mostly rock. The locks themselves were made of 1,564,400 m³ (2,046,100 cubic yards) of concrete.
The quantity of material needed to construct the locks required extensive measures to be put in place to handle the stone and cement. Stone was brought from Portobelo to the Gatun locks; the work on the Pacific side used stone quarried from Ancon Hill.
Huge overhead cableways were constructed to transport concrete into the construction at Gatun. 26 metre (85 ft) high towers were built on the banks of the canal, and cables of 6 cm (2.5 inch) steel wire were strung between them to span the locks. Buckets running on these cables carried up to six tons of concrete at a time into the locks. Electric railways were constructed to take stone, sand and cement from the docks to the concrete mixing machines, from where another electric railway carried two 6-ton buckets at a time to the cableways. The smaller constructions at Pedro Miguel and Miraflores used cranes and steam locomotives in a similar manner.
Concrete is normally moulded in formwork, temporary structures which give shape to the concrete as it sets. For a simple construction, these would normally be made quite simply of wood, but the scale of the locks demanded extraordinary forms.
The forms for the walls consisted of towers, fronted with braced vertical sheets, 19 cm (7½ inches) thick, mounted on rails to allow the locks to be constructed in sections; a section of lock would be poured behind the form, and when it was set, the form would be moved to do the next section. Each of the twelve towers was 23.8 m (78 ft) high by 11.0 m (36 ft) wide. The forms for the culverts were made of steel, and were collapsible so they could be removed and moved along after each section of culvert had set. There were, in all, 33 forms for the centre and side-wall culverts, each 3.7 m (12 ft) long; and 100 smaller forms for the lateral culverts.
The Pacific-side locks were finished first; the single flight at Pedro Miguel in 1911 and Miraflores in May, 1913.
The seagoing tug Gatun, an Atlantic entrance working tug used for hauling barges, had the honor on September 26, 1913, of making the first trial lockage of Gatun Locks. The lockage went perfectly, although all valves were controlled manually since the central control board was still not ready.

The Bridge of the Americas

The Bridge of the Americas (Spanish: Puente de las Américas; originally known as the Thatcher Ferry Bridge) is a road bridge in Panama, which spans the Pacific entrance to the Panama Canal. Completed in 1962, at a cost of US$20 million, it was the only non-swinging bridge (there are two other bridges, one at the Miraflores locks and one at the Gatun locks) connecting the north and south American land masses until the opening of the Centennial Bridge in 2004. The bridge was designed by Sverdrup & Parcel.

The Bridge of the Americas crosses the Pacific approach to the Panama Canal at Balboa, near Panama City. It was built between 1959 and 1962 by the United States at a cost of 20 million U.S. dollars. From its completion in 1962 until the opening of the Centennial Bridge in 2004, the Bridge of the Americas was a key part of the Pan-American Highway. The Bridge of the Americas greatly increased road traffic capacity across the canal. There are two earlier bridges which cross the canal, but they use moveable designs and have limited traffic capacity. The earlier spans include a small swinging road bridge (built into the lock structure at Gatún) and a swinging road/rail bridge (constructed in 1942 at Miraflores.) The Centennial Bridge was constructed to eliminate this bottleneck and reduce traffic congestion on the Bridge of the Americas.
The bridge is a cantilever design where the suspended span is a tied arch. The bridge has a total length of 1,654 m (5,425 ft) in 14 spans, abutment to abutment. The main span measures 344 m (1,128 ft) and the tied arch (the center part of the main span) is 259 m (850 ft).The highest point of the bridge is 117 m (384 ft) above mean sea level; the clearance under the main span is 61.3 m (201 ft) at high tide. Ships must cross under this bridge when traversing the canal, and are subject to this height restriction. (The Centennial Bridge is also a fixed obstacle, but its clearance is much higher: 80.0 m (262 ft)).
The bridge is an impressive sight, and a good view can be obtained from the Balboa Yacht Club, where many small boats tie up before or after transiting the canal. Throughout the day and night numerous vessels pass under the bridge, either entering or departing from the Panama Canal. There are wide access ramps at each end, and pedestrian walkways on each side


The need for a bridge

From the beginning of the French project to construct a canal, it was recognised that the cities of Colón and Panamá would be split from the rest of the republic by the new canal. This was an issue even during construction, when barges were used to ferry construction workers across the canal.
After the canal opened, the increasing number of cars, and the construction of a new road leading to Chiriquí, in the west of Panama, increased the need for some kind of crossing. The Panama Canal Mechanical Division addressed this in August 1931, with the commissioning of two new ferries, the Presidente Amador and President Washington.[2] This service was expanded in August 1940, with additional barges mainly serving the military.
On June 3, 1942, a road/rail swing bridge was inaugurated at the Miraflores locks; although only usable when no ships were passing, this provided some relief for traffic wishing to cross the canal. Still, it was clear that a more substantial solution would be required. To meet the growing needs of vehicle traffic, another ferry, the Presidente Porras, was added in November 1942

The bridge project

The idea of a permanent bridge over the canal had been proposed as a major priority as early as 1923. Subsequent administrations of Panama pressed this issue with the United States, which controlled the Canal Zone; and in 1955, the Remón-Eisenhower treaty committed the United States to building a bridge.
A contract of $20,000,000 was awarded to John F. Beasly & Company who built the bridge out of steel and reinforced concrete, and the project was initiated in a ceremony which took place on December 23, 1958, in the presence of United States Ambassador Julian Harrington, and Panamanian President Ernesto de la Guardia Navarro. Construction began on October 12, 1959, and took nearly two and a half years to complete.
The inauguration of the bridge took place on October 12, 1962, with great ceremony. The day began with a concert by the bands of the U.S. Army and Air Force, and the Panama National Guard; this was followed by speeches, prayers, music, and the national anthems of both nations. The ribbon was cut by Maurice H. Thatcher, after which those present were allowed to walk across the bridge. The ceremony was given full nationwide coverage on radio and television; significant precautions were taken to manage the large crowds of people present. These proved inadequate, however, and pro-Panamanian protesters disrupted the ceremony, even removing the memorial plaques on the bridge.


When opened, the bridge was an important part of the Pan-American Highway, and carried around 9,500 vehicles per day; however, this expanded over time, and by 2004 the bridge was carrying 35,000 vehicles per day. The bridge therefore became a significant bottleneck on the highway, which led to the construction of the Centennial Bridge, which now carries the Pan-American Highway too. On May 18, 2010, the bulk cargo ship Atlantic Hero struck one of the protective bases of the bridge after losing engine power, partially blocking that section of the canal to shipping traffic. The bridge did not receive damage and there were no fatalities. On December 2010, the Centennial Bridge access road collapsed in a mudslide, and commercial traffic was diverted to the Bridge of The Americas.[4][5] In April, 2011 limited two-way traffic over the Centennial Bridge was restored, however As of June 2011 the Centennial bridge is not expected to return to full capacity until Fall 2011, leaving heavier than normal traffic on the Bridge of the Americas

The name

The bridge was originally named Thatcher Ferry Bridge, after the original ferry which crossed the canal at about the same point. The ferry was, in turn, named after Maurice H. Thatcher, a former member of the canal commission, who introduced the legislation which created the ferry. Thatcher cut the tape at the inauguration of the bridge.
The name was unpopular with the government of Panama, however, which preferred the name "Bridge of the Americas". The Panamanian view was made official by a resolution of the National Assembly on October 2, 1962, ten days before the inauguration. The resolution read as follows:
The bridge over the Panama Canal shall bear the name Bridge of the Americas. Said name will be used exclusively to identify said bridge. Panamanian government officials shall reject any document in which reference is made to the bridge by any name other than "Bridge of the Americas". A copy of this resolution, with the appropriate note on style, shall be forwarded to all legislative bodies of the world, so that all may give the bridge the name chosen by this honorable assembly, complying with the express will of the Panamanian people. Given in the city of Panama on the second day of the month of October of nineteen hundred and sixty-two.
President, Jorge Rubén Rosas
Secretary, Alberto Arango N.
During the inauguration ceremony (which was concluded with the playing of the "Thatcher Ferry Bridge March"), U.S. Under Secretary of State George Wildman Ball said in his speech: "we can look today to this bridge as a new and bright step toward the realization of that dream of a Pan-American Highway, which is now almost a reality. The grand bridge we inaugurate today — truly a bridge of the Americas — completes the last stage of the highway from the United States to Panama".
Nonetheless, the official name of the bridge became the "Thatcher Ferry Bridge" and remained so until Panamanian control in 1979.
Postage stamps were issued with the name "Thatcher Ferry Bridge." In the postage stamps and postal history of the Canal Zone they are well known for an error on one sheet where the bridge is missing.


Monkey Island Tour


Monkey Island is located at Gatun Lake in the valley of the Chagres river between Panama and Colon Provinces in the Republic of Panama.  Its surface area is 164 square miles. Gatun lake is the second largest artificial man-made lake in the world. This lake was created in 1907 and took 6 years to flood. It was created to help the transit of ships across the isthmus. This lake is the reservoir of water needed for the operation of the Panama Canal. It is surrounded by nature and history everywhere – the flora and fauna makes this place a must-see while visiting Panama.

The Monkey Island Day Tour is boat exploration of Lake Gatun and a great opportunity to see 4 different species of monkey, all within 40 minutes of Panama’s capital city. You will also see many other animal species such as Crocks, Toucans, Sloths and many exotic birds. The tour also gives you the chance to bathe in spring fed natural pools and kayak in the lake.

What is included with the Monkey Island Day Tour?
  • Encounter Capuchin, Howler, Tamarin and a fourth surprise specie of Monkey.
  • See Crocks, exotic birds, Sloths, Turtles, Iguanas and Many other jungle animals
  • A water level look at Panama Canal ships as they pass through Gatun Lake.
What to bring ? : Bring Bathing clothes, water shoes, bug repellent and sun block.
Gray-Bellied Night Monkey

Lemurine Owl Monkey is another name known for this night monkey. The gray-bellied night monkey is a small monkey native of Panama and possibly some forests of south america. It is an arboreal and nocturnal specie with a vulnerability to extinction. Their fur goes from gray-brown to reddish-brown, short tail and large brown eyes.

The gray-bellied night monkey likes to sleep at daytime and eats at night. It looks for fruit, insects, nectar, leaves and sometimes small birds or mammals.
This is a monogamous monkey. Most of the times the couple has only one infant per year, twins are rare. The mother is in charge of the nursing only but the father takes care of baby.
Geoffroy’s Tamarin Monkey

Geoffroy’s tamarin monkey is a small monkey found in Panama and Colombia. It is black and white with a red-brownish nape and a white triangle-shaped patch in the front of his head. The geoffroy’s tamarin monkey that you will see during your Monkey Island Panama tour is the smallest one in Central America. They like to live in dry and moist tropical forests specially in the Panama Canal zone.

The geoffroy’s tamarin monkey likes to eat fruits, plants, insects and exudates. Most of the tamarin females give birth between april to june. The newborns look different than their parents, they have a beige color blaze, white face and black fur all over their bodies including the tail. All the family helps with the baby care including siblings. Mother and father carry them and groom them too. They start to be independent when they are about 15 weeks old.  The geoffroy’s tamarin monkey has a lifespan of 13 years.

The white-faced capuchin monkey

The white-faced capuchin monkey is also known as White-throated Capuchin or White-Headed Capuchin is native of Central America and northern South America. They live in groups of 20 males and females. This is a very intelligent and versatile monkey who can adapt to live in different types of jungle. Most of them have black fur with white or yellow face and neck.

The capuchin monkey eats fruit, plants, invertebrate animals and small vertebrate ones. They use some plants and branches as a tool to get food when its out of reach. The capuchin monkey living in the Gatun area of the Panama Canal use to rub their fur against some plants as a treatment for fungus, bacteries, ticks, etc. Their lifespan is about 50 years.

The mantled howler monkey you will see in the Monkey Island Panama tour likes to live in groups of females with a few males. It is native of the area of Central America

The mantled howler monkey communicates with other members of their group doing a very loud sound that can be heard for 5 Kms and is considered as the loudest animal of the panamanian fauna.  Their diet consists mostly of leaves from the top of trees, fruits, nuts and flowers. Their lifespan is between 15 to 20 years

Mariano Rivera


New York Yankee closer Mariano Rivera’s save number 602 may well have been the most anticlimactic record breaking moment in major league baseball history. Everyone knew that barring some disaster or injury it was inevitable.

And Rivera did not need to break Trevor Hoffman’s record of 601 saves to prove that he is the greatest closer of all-time. He has already proven it time and again over the course of 17 seasons, 15 trips to the post season and seven World Series.
All Rivera did while breaking the record was reaffirm his greatness.

Baseball is full of record breaking moments. Usually when they happen baseball historians are quick to debate.

They ask who was better, the player who had the record or the one who broke it? Or how does the record compare to other records? Was it thought to be unbreakable or just a number for others to shoot for?
There was none of this with Rivera. Everyone knows that he is a better closer than Hoffman. And everyone knows that when he is done the record may very well last for a long time.
Looking back what other record breaking moments seemed anticlimactic?
Not many.
When San Francisco Giant Barry Bonds hit home run number 756 to break Henry Aaron’s record, it was met more with disdain than joy by many. The fans in San Francisco who saw it were thrilled, but many did not celebrate Bonds’ accomplishments because of the long shadow of performance enhancing drugs which dogged him.
When the 1976 Cincinnati Reds became the first team to sweep the league championship and World Series it was thought to be a great accomplishment, but the Reds were defending world champions and better that season than they were in 1975. Many predicted that they would go undefeated in the post season.
Los Angeles Dodgers pitcher Orel Hershiser set the record for consecutive scoreless innings in 1988 with 59 breaking the record of 58 2/3 by former Dodger Don Drysdale in 1968. While Drysdale’s record was celebrated then and for the next 20 years, Hershiser’s was met with less excitement for two reasons.

First he set it on the west coast while most of America was asleep.
Second he had such a great post season in leading the Dodgers to a world’s championship that people remember him more for that.

On the day that Rickey Henderson set the all-time stolen base record in 1990 it was the lead story until pitcher Nolan Ryan threw his record setting seventh no hitter that night. Everyone knew that Henderson was going to set his record, but no one knew Ryan would throw another no hitter.

At the time that all of these records were set each was considered to be a great moment. And each begged the question of what was the players place in history and where did the record rank.
Not Mariano Rivera’s saves record. Mo already had his place in history.This made a great moment seem anticlimactic.


Lulling hitters into a false security with his fluid, effortless-looking delivery, Mariano Rivera's explosive fastball thrust him into a critical role on the 1996 World Champion Yankees with less than half a year of major-league experience. A year later, he established himself one of the league's top closers after reigning World Series MVP John Wetteland signed with the Texas Rangers.
The son of a fisherman, Rivera was born in 1969 in Panama City, Panama. He signed with the Yankees in February of 1990 and immediately opened some eyes by posting a 0.17 ERA in 52 innings for the Yankees' Single-A affiliate in Tampa.

In the minor leagues, Rivera rarely spent time in the bullpen. His major league debut in May 1995 came as a starter, facing All-Star lefthander Chuck Finley in Anaheim Stadium. Finley struck out 15 as the Angels pasted Rivera for five runs and eight hits in 3 1/3 innings. But Rivera picked up his first major league win five days later against the A's in a 4-1 win at the Oakland Coliseum.

In his first season with New York, Rivera appeared in nineteen games, starting ten, and although he finished with a 5.51 ERA he showed flashes of his burgeoning talent. His most impressive start of the season came against Chicago on July 4, when he struck out eleven White Sox (the most by a Yankee rookie since Al Leiter in 1988) in a two-hit shutout at Comiskey Park.
Rivera, who spent most of the month of June in Columbus, nursing a sore shoulder, had nearly been traded to the slumping Detroit Tigers for starter David Wells. "I didn't say yes, and I didn't say no," Yankee GM Gene Michael said of the Tigers' offer. "I'm glad I didn't have to." When Rivera's velocity hit 96 MPH in a rain-shortened, five-inning no-hitter in Triple-A, Michael's mind was made up. Rivera was staying.

By the end of the season, Rivera had shown manager Buck Showalter enough for the Yankee skipper to keep him on the team's post-season roster when New York clinched a wild-card berth. In the Yankees' harrowing five-game loss to Seattle in the Division Series, Rivera came of age. Pitching three times against a fearsome Mariners lineup, Rivera was the Yankees' most reliable arm in the series, hurling 5 1/3 scoreless innings while striking out eight, including a key whiff of Mike Blowers with the bases loaded in Game Five.
By the following season, the Yankees had concluded that Rivera wouldn't survive as a starter without another dependable pitch to complement his devastating fastball. When Rivera began mowing down American League hitters with regularity, shifting the slender right-hander to the bullpen looked like a stroke of genius. Although Rivera occasionally worked in a slider or changeup, he relied almost exclusively on a rising fastball that routinely topped 95 miles per hour. With little need to throw pitches out of the strike zone, Rivera simply dared batters to hit the fastball. Far more often than not, they couldn't.
As the setup man for closer John Wetteland, Rivera gave the Yankees an airtight bullpen tandem. Most often, if New York could keep a lead through six innings, the game was over. Rivera would pitch the seventh and eighth, and Wetteland closed the door in the ninth. Indeed, Rivera enjoyed such dominance in his new setup role that people began touting him as a Cy Young and MVP candidate.
His numbers for the year were eye-popping. His 130 strikeouts were the most ever for a Yankee reliever. In 107 2/3 innings Rivera allowed just 73 hits (right handed batters hit just .157 against him) and only one home run. While winning eight games and saving five against three defeats, Rivera posted a 2.09 ERA. From April 19 through May 21 he threw 26 consecutive scoreless innings, a stretch which included fifteen straight hitless innings. Only ten of 61 first batters he faced that season managed to reach base.
In the playoffs that season, Rivera was even better. He pitched 4 2/3 scoreless innings against Texas in the Divisional Series, and hung up four goose eggs against Baltimore in the League Championship Series (picking up the win with two innings in New York's Game One, Jeffrey Maier-aided triumph). "Reminded me of myself a long time ago," said teammate Dwight Gooden of Rivera's performance. In the World Series against the heavily favored Atlanta Braves, Rivera allowed just one run in 5 2/3 innings, pitching a scoreless eighth in the Yankees' 3-2 title-clinching win in Game Six.
Although 1997 wasn't the unqualified success the previous season had been, it was a crucial year in the course of Rivera's career. John Wetteland had signed with Texas in December 1996, leaving the Yankees' ninth-inning fortunes in Rivera's hands. At first, Rivera struggled with the pressure of his new role, blowing three of his first four save opportunities, including the home opener. But Rivera righted himself soon enough; his 27 saves at the midseason break earned him his first trip to the All-Star Game. By retiring Charles Johnson, Mark Grace, and Moises Alou, Rivera became the first Yankee to save a Midsummer Classic. For the season he ended up with 43 saves in 52 chances; although his ERA dropped to 1.88, opponents' batting average rose from .189 to .237 and his strikeout totals fell below one an inning.
Probably the worst moment of Rivera's young career came in Game Four of a Division Series dogfight against the Cleveland Indians at Jacobs Field. The Yankees led the Series two games to one, and were four outs away from advancing to the LCS when Torre called on Rivera to take over from Mike Stanton to preserve a one-run lead against the Tribe. Rivera promptly gave up an opposite-field home run to Sandy Alomar, Jr. that fell just beyond the reach of rightfielder Paul O'Neill, tying the game and reviving the Indians. Cleveland won the game in the bottom of the ninth and pulled out another close victory in Game Five to send the discouraged New Yorkers home for the winter.
Forged in the crucible of that bitter defeat, however, was the resolution that inspired an extraordinary 1998 season. Rivera, now fully acclimated to the closer's role, saved 36 games in 41 opportunities, allowing just 48 hits in 61 1/3 innings as the Yankees set an American League record with 114 wins. The playoffs seemed a mere formality, and the Yankees lost just two games en route to their 24th world championship. Rivera, whose first cousin Ruben sat in the opposing dugout for the NL Champion Padres, was at his dominating best, allowing no runs while saving three games.
1999 brought more of the same for the man now generally regarded as the top closer in baseball. He saved 45 games out of 49 opportunities, including his final 22 chances. By developing a cut fastball, Rivera became a more efficient pitcher, relying less on strikeouts and more on the aid of his defense. Winning his third world championship with the Yankees, Rivera was awarded World Series MVP for collecting two saves and one victory against the Atlanta Braves. After tossing 12 scoreless innings in the Yankees' playoff run, his career 0.38 post-season ERA (two runs in 47 1/3 innings) ranked as the lowest in baseball history.
A deeply religious man, Rivera financed the construction of a church in his native Panama City and can often be seen reading the Bible in the Yankees' clubhouse. At a church service honoring him in Panama after the 1999 season, he announced that he would spend four more years in baseball and then retire to become an evangelical minister.
Despite losing in arbitration to the Yankees in February 2000, Rivera's new $7.25 million contract was the most money ever awarded in an arbitration settlement. (AGL)

The Pollera from Panama

The Pollera the national costume of Panama and one of the most beautiful and most admired typical dresses of the world.

The formal pollera, used for festive occasions and holidays, is made of fine white linen, cambric or voile. At least 12 yards of material is used to make a pollera. A traditional pollera has a pure white background so that the blended tints of embroidered designs will stand out. These designs traditionally are of flowers, birds, garlands, or other combinations of designs, preferably of native origin and feeling. Exquisite designs are made in cross-stitch or by the use of a more elegant needlework known as "talco en sombra," or applique which is characteristic of Panama. It consists of two pieces of material sewn together. A design is made on one piece of the fabric, the design is then carefully cut out and its edges turned under and sewn to the background with tiny invisible stitches.

The formal pollera consists of the blouse (wider than the montuna blouse), the skirt and the petticoat or petticoats, as one to as many as three are worn under the gown. The blouse of all three polleras is white and worn off the shoulder. For the formal dress, the blouse has a neck band at the top of the bodice made of the traditional "mundillo," a fine handmade bone lace made in the Interior of Panama, which is edged with a heavier lace. The band has openings in the front and in the back, where wool pompons are placed. The neck band is interwoven with wool, the same color as the pompons. Two ribbons, called "gallardetes," hang from the waist, one in front and one in the back, and match the color of the wool. The heelless shoes, soft slippers in velveteen or satin, are also the same color as the wool pompons. No stockings are worn

A beautifully embroidered ruffle of fine wide Valencian lace is attached to the mundillo band and falls to the middle of the bodice. Another ruffle is added under the first one and this falls to the waist, or to a little lower than the waist. Both of these ruffles are exquisitely embroidered or worked in applique. The blouse has push-up sleeves with an embroidered ruffle, also trimmed in lace.

The skirt of the formal pollera is always made of fine white material, fine enough for the handwork on the petticoats to show through. It is loose, full and long, reaching the ankles. The skirt is put together in two pieces; the upper section comes to the knees and is separated by an insertion of mundillo lace, with the material heavily gathered so it can be spread out and be admired. Twice as much fabric goes into the lower part of the skirt, making a circle. The edge of the skirt is trimmed with about 25 yards of lace, 4 or 5 inches wide. The magnificent skirt is gathered at the waist and tied by four narrow ribbons, two crossing in the front and two in the back, running through the button holes of two gold buttons at either side of the waist.

The petticoats are handmade of very fine white linen, as elaborate as the skirt, with laces, cutwork and embroidery.

The feet of the dressed up woman, are covered with shoes made from velvet, and don't have heels. This shoes, back in the times of the aristocracy, were adorned with gold clasps and it holds onto the feet with laces, and embroideries, making a contrast with the beauty and richness of the gold jewelry and the tipico dress.

The hairdress is an important part of the pollera. The hair is parted in the center and tightly pulled back behind the ears, forming two braids. The braids are covered with several pairs of tembleques
The woman’s head is decorated with curved combs, decorated in gold filigree; a main large tortoise shell comb decorated with repoussé or engraved gold strips; and small decorative gold square temple patches (reminiscent of pain patches). Very elaborate gold earrings of a great variety are also worn. Around the combs on both sides and on the back of the head, natural white carnations are worn, or more commonly, delicate custom pearl bead flower, butterfly, or dragonfly shapes with gold or silver wire twists on pins cover the hair, resulting in a beautiful, elegant headdress.

About the jewelry that she carries, these are so attractive, of luxurious and expensive design, that anyone could say that the panamanian woman dressed with a pollera is one of riches, however, every piece, necklace, ring and peineta forms a part of her legacy that is kept and that will adorn the polleras of future generations.

Around the neck, a gold filigree choker with small flower shapes, a slightly longer black ribbon choker with a coin modal or a golden cross. The main necklace is the long, Flat Chain with flat intertwined links with beautiful pendants that hangs around mid-chest level. The Betwitching Chain, very similar to the flat chain necklace, despite being of a similar length, can be gathered in the palm of the hand. The Solomon chain, made of links in the shape of columns; the scapular and the rosary, all delicate and made of gold, also hang gracefully from the neck.
